WS-Eventing extension sends incorrect HTTP content-type

The Subscription class in org.jboss.ws.extensions.eventing.mgmt contains hard-coded SOAP 1.2 envelopes for event notification and SubscriptionEnd messages. However, SOAPConnectionImpl::callOneWay() sets the HTTP content-type to "text/xml". (More specifically, SOAPMessageImpl::saveChanges() does.)

The SOAP 1.2 specification (7.1.4) and RFC 3902 require that SOAP HTTP bindings use a content-type of "application/soap+xml".

This appears to be a bug. In my case, it manifests itself by when Axis2 throws a SOAPProcessingException complaining that incoming transport level information do not match the SOAP namespace.

I would suggest that Subscription provide the correct content-type in a MimeHeaders object to its MessageFactory::createMessage() call, but SOAPMessageImpl::saveChanges() overwrites the value indiscriminately. Is changing those hard-coded envelopes to SOAP 1.1 the best solution here? It seems like we should be able to make SOAP 1.2 work...
